I've got LTE doing around 18Mbps. 4K is a breeze on Netflix with it, so I'm going to wager that 20/20 is fine. more is better though, as you don't want to start stuttering when your phone decides to update while you're watching a movie.

It depends, will the line be used for anything else or just exclusively for watching 4k streaming? Reason why I ask is that if you want to use the line for lets say VOIP or gaming, you will have to double or triple the speed. latency sensitive applications need the extra headroom.

Hi Dolby. You are quite right, if the question here has to do with latency issues and/or diagnosing problems with a line. The original post has to with line speed and 4k streaming. Please lets keep it on topic. If you utilize the line 100% then packets will be dropped, latency sensitive applications will be affected to various degrees. I come back to my original question, will the line be used exclusively for 4k Streaming, or shared with other applications. If yes, then build in enough headroom and you don't have to worry about the exact spec for 4k.
